| 摘 要： | 研究了在新型的模糊Lyapunov方法下连续T-S模糊控制系统稳定性和模糊控制器设计问题,首先,得出了自由系统新的稳定性充分条件,这个条件具有更大的宽松性;然后基于一系列线性矩阵不等式设计了模糊控制器,这些矩阵不等式可以利用凸优化技术来进行解决。通过对两个具体的实例的仿真验证了本算法的有效性。

| Abstract: | The stability analysis and fuzzy controller design problem of T-S continuous-time fuzzy system were discussed based on news fuzzy Lyapunov method. First, a new sufficient condition of the stability of the autonomous system was proposed, and the condition was more relaxed. Then the fuzzy controller was designed based on a series of LMls, and the obtained LMIs could be solved by convex optimization. The simulation of two examples shows that these methods are effective. |
